CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application Ser. No. 62/423,051 filed Nov. 16, 2016, which is incorporated herein in its entirety by reference.

FIELD

The present disclosure generally relates to modular building units such as prefabricated rooms adapted for quick on-site installation and construction. More specifically, the present disclosure relates to systems and methods for manipulating, positioning, and installing prefabricated building units or “pods”.

BACKGROUND

Onsite labor is a major cost associated with constructing buildings, particularly when such labor is conducted at higher elevations such as in high-rise construction. Labor rates are known to increase with height for a number of reasons including the necessity of moving project materials by crane or elevator. At higher elevations, movement of materials and pace of labor slows down, increasing construction schedule times and adding to the overall construction cost.

Modern methods of constructing buildings including high-rise structures include the provision and use of modular elements or “pods”, wherein a room or portion of a final structure is prefabricated as a unit, delivered to a site as a substantially finished unit, and installed into the larger structure. For example, one or more bathrooms intended to be provided as individual rooms in a finished building structure may be assembled off-site, shipped to the construction site, and installed as units.

U.S. Patent Application Publication No. 2008/0236056 to Hourihan, which is hereby incorporated by reference in its entirety, discloses a modular building structure. Although some features of modular units of Hourihan are contemplated for use with embodiments of the present disclosure, Hourihan fails to disclose various features of the present invention including, but not limited to, methods and devices for moving and installing modular rooms and pods.

U.S. Patent Application Publication No. 2007/0294954 by Barrett et al. generally describes a prefabricated bathroom assembly as well as methods of manufacturing and installing prefabricated bathroom assemblies. The bathroom assembly of Barrett et al. can be used with the methods and devices of the present disclosure. However, Barrett et al., which is incorporated herein in its entirety by reference, does not disclose various features of the present disclosure, including at least the methods and devices for manipulating, positioning, and installing prefabricated building units described herein.

U.S. Patent Application Publication No. 2011/0056147 to Beaudet, which is hereby incorporated by reference in its entirety, discloses a construction pod or module and methods of installing the same. The installation methods and devices of Beaudet, however, generally comprise conventional cranes and similar equipment. Beaudet fails to disclose various features of the present invention including, for example, methods and devices for fine-tuning the placement and final positioning of a module or pod.

U.S. Patent Application Publication No. 2013/0086849 to Clouser et al., which is hereby incorporated by reference in its entirety, discloses a modular bathroom pod. Clouser et al., however, fail to disclose devices and methods for positioning and installing such a pod, at least as provided by embodiments of the present disclosure.

U.S. Patent Application Publication No. 2013/0152485 to Austin et al., which is hereby incorporated by reference in its entirety, discloses modular building units that are adapted for installation on-site. Various features and methods of constructing building units and pods as disclosed in Austin et al. are contemplated for use in embodiments of the present disclosure. Austin et al., however, fails to disclose various features, methods and devices of the present disclosure including methods and devices for fine-tuning the positioning and final installation location of a pod.

Existing modular building units are typically constructed with a relatively thick structural floor, commonly made of steel or concrete. Known flooring systems for existing pods typically comprise six-inch elevated floors. Alternatively, existing units or pods may be delivered to a location or installation site without a floor. The pod is then finished in the field.

When a modular building unit or pod is delivered to a construction site for installation in a building structure, the pod must typically be moved into alignment with walls of the building. The pod may also be aligned with utility connections. However, existing methods and devices for positioning pods with respect to walls and utility connections present a number of challenges and serve to increase labor costs and risks to workers on-site.

Accordingly, there is a need for improved systems and methods for manipulating, positioning, and installing prefabricated building units or pods within a building structure.

SUMMARY

In one aspect of the present disclosure, a system and device for positioning a modular building unit is provided. In certain embodiments, modular building units and pods are provided with a honeycomb composite floor member. Optionally, the floor member is between about 0.4 and about 0.6 inches thick. The provision of floor units in accordance with the embodiments of the present invention provides a solution to existing problems related to door thresholds. Accepted building methods in the United States do not allow four or six-inch pod depressions or excessive slab toppings. Accordingly, embodiments of the present disclosure provide a thin floor member to accommodate building methods of the United States and wherein the floor of a pod unit can be provided substantially flush with an associated building upon installation.

Embodiments of the present disclosure contemplate providing a thin floor member, which reduces overall weight of a pod or unit and provides various enhancements in construction efficiency. However, the thinner floor also comprises less structural integrity than a thicker, conventional floor. Thinner floors may be subject to bending stresses and damage, particularly during shipping and installation of a pod. In order to accommodate for the reduced structural integrity of a thinner floor, methods and devices of the present invention contemplate providing one or more pods on a pallet or similar support. Embodiments of the present disclosure further contemplate the provision of lifting and supporting devices to enable removal of a pallet or similar device, particularly in confined spaces and/or corner-installations.

Embodiments of the present disclosure contemplate providing or positioning a modular building unit in a corner such that at least two walls or panels of the unit are provided substantially adjacent to walls of larger buildling structure. Two other walls of the unit are configured to face away from the walls of the building structure. Such positioning necessarily requires that the unit be held, supported, or otherwise manipulated on the two free walls or panels that are not intended to be placed in a corner. This positioning provides various challenges, as will be recognized by one of ordinary skill in the art, and serves to increase labor costs and risks to workers. Methods and devices as shown and described herein provide for a more efficient means of positioning a modular building unit, including removing the unit from a pallet or similar shipping device, and efficiently positioning the unit without complex attachment of heavy equipment, counterweights, etc.

In one aspect of the present disclosure, a lifting and moving assembly for modular building units is provided. The assembly comprises a base member comprising a plurality of rollers. The base member is moveable with respect to the modular building unit. The lifting and moving assembly can optionally include a track member for placement on a ground or surface. The rollers of the base member can be aligned with the track member.

The base member is pivotally interconnected to a frame member. In one embodiment, a plurality of linkages are rotatably connected to the base member and to the frame member.

The frame member includes a support member. In one embodiment, the support member extends substantially horizontally. A plurality of load-bearing hooks are provided on the support member. The support member and the load-bearing hooks are operable to receive and support the weight of a modular building unit. The support member is in force-transmitting communication with the plurality of linkages, and a displacement of the linkages about the connection between the linkages and the base member causes a corresponding arcing displacement of the support member.

Another aspect of the present disclosure includes methods of moving, lifting, and installing modular building units. In one embodiment, a method is provided comprising: (1) providing a lifting and moving assembly which includes at least a support member and a plurality of linkages; (2) providing a modular building unit on the lifting and moving assembly such that the modular building unit is in communication with the support member; (3) inducing a movement of the plurality of linkages and the support member to move the modular building unit, the movement providing the modular building unit in a desired location; and (4) removing the lifting and moving assembly from the modular building unit. In one embodiment, inducing a movement of the plurality of linkages can include moving the modular building unit vertically. Additionally, the lifting and moving assembly can move the modular building unit in a direction substantially parallel to at least one wall of the modular building unit.

One aspect of the present disclosure is an assembly for lifting and moving objects. The assembly includes one or more of, but is not limited to: (1) a track member for placement on a surface that is generally horizontal; (2) a base member that is movable along a length of the track member; (3) a plurality of linkages, each linkage being rotatably connected to the base member; (4) a support member in force-transmitting communication with the plurality of linkages, the support member extending substantially parallel to the track member; and (5) a plurality of load-bearing hooks provided on the support member, the support member and the load-bearing hooks operable to receive and support the weight of an object, wherein a displacement of the linkages about connections between the linkages and the base member causes a corresponding displacement of the support member in a direction generally parallel to the track member. The displacement of the linkages also causes an arcing displacement of the support member which alters a distance between the surface and the support member. In this manner, in one embodiment, the displacement of the linkages about the connections causes a vertical and a horizontal displacement of the support member. In one embodiment, the object is modular building unit. Optionally, the modular building unit is a prefabricated room for a building.

In one embodiment, the base member includes a plurality of rollers. Optionally, the rollers have a notch configured to engage a protrusion of the track.

In one embodiment, the assembly further includes a frame member rotatably connected to each linkage. In another embodiment, the assembly includes a drive member interconnected to the base member and the frame member, the drive member configured to displace the linkages about the connections. Optionally, each linkage can rotate between approximately 0° and approximately 100° relative to the base member. Altering an angle of the linkages alters a position of the frame member relative to a length of the base member.

The support member is associated with the frame member. In one embodiment, the support member is configured to rotate such that a free end of each of the load-bearing hooks is rotatable into a position to engage the object. In another embodiment, at least a portion of each of the load-bearing hooks extends beyond a plane defined by the frame member when the hooks are in the position to engage the object. Optionally, the load-bearing hooks can be repositioned along a length of the support member.

Another aspect is a positioning device to lift and move a building pod. The device comprises one or more of: (1) a base member configured to move on a surface; (2) two or more linkages, each linkage including a first end and a second end, the first end being pivotably interconnected to the base member; (3) a frame member pivotably interconnected to the second end of each linkage; (4) a support member rotatably interconnected to the frame member; and (5) a plurality of hooks positioned on the support member and configured to selectively engage the building pod, wherein altering an angle of the two or more linkages relative to the base member alters a distance between the hooks and the surface. Altering the angle of the two or more linkages also alters a position of the hooks relative to a length of the base member. More specifically, in one embodiment, altering the angle of the two or more linkages alters a position of the frame member relative to the length of the base member. In one embodiment, the building pod is a prefabricated room for a building. In another embodiment, the building pod is a prefabricated bathroom.

Optionally, the device includes a drive member. The drive member is configured to alter the angle of the two or more linkages relative to the base member. In one embodiment, the drive member is threadably interconnected to one of the base member and the frame member.

In one embodiment, rotating the support member in a first direction moves each of the plurality of hooks to a support position to engage the building pod. In another embodiment, at least a portion of each of the plurality of hooks extends beyond a plane defined by the frame member when the hooks are in the support position. Optionally, each of the plurality of hooks can be selectively repositioned along a length of the support member.

The base member may optionally include at least two wheels. In one embodiment, the at least two wheels are configured to engage an optional track positioned on the surface. In another embodiment, the at least two wheels include a circumferential recess to engage a protrusion of the optional track. The circumferential recess has a “V” shape in one embodiment. Optionally, the track has a corresponding “V” shape with an apex positioned distal to the surface.

Yet another aspect of the present disclosure is a method of lifting and moving an object, such as a modular building unit. The method includes, but is not limited to: (1) aligning a first positioning device with a first side of the object; (2) aligning a second positioning device with a second side of the object; (3) moving hooks of the first and second positioning devices to engage the object; (4) inducing a movement of a plurality of linkages of the first and second positioning devices to move the object into a desired location; and (5) moving the hooks of the first and second positioning devices to disengage the object. In one embodiment, the object is a modular building unit. Accordingly, in one embodiment, the first side of the object is a first wall and the second side of the object is a second wall.

In one embodiment, the movement of the plurality of linkages alters an angle of the linkages with respect to lengths of the first and second positioning devices. In this manner, the movement of the plurality of linkages causes a movement of the object along a horizontal axis and a movement along a vertical axis.

In one embodiment, aligning the first and second positioning devices further comprises positioning the first positioning devices substantially parallel to the second positioning device. In another embodiment, the first and second positioning devices can be interconnected.

In another embodiment, inducing a movement of the plurality of linkages causes both a vertical movement and a horizontal movement of the object, the horizontal movement being substantially parallel to lengths of the first and second positioning devices.

Optionally, the method may further include inducing a longitudinal movement of the first and second positioning devices along a horizontal surface. In one embodiment, the longitudinal movement is along optional first and second tracks positioned on the horizontal surface. In another embodiment, the method includes aligning the first track with the first wall and aligning the second track with the second wall. The method may also include engaging wheels of the first positioning device with the first track and engaging wheels of the second positioning device with the second track.

In one embodiment, moving the hooks of the positioning devices includes rotating first and second support members of the first and second positioning devices. In one embodiment, moving the hooks to engage the object comprises rotating a least a portion of each of the hooks to extend beyond plane defined by the respective first and second positioning devices.

In another embodiment, inducing a movement of the plurality of linkages comprises changing an angle of the linkages with respect to a horizontal surface. In one embodiment, the linkages can rotate between approximately and approximately 100° relative to the horizontal surface. In another embodiment, inducing the movement of the plurality of linkages includes activating first and second drive members associated with the respective first and second positioning devices. In one embodiment, activating the first and second drive members comprises rotating the drive members.

DETAILED DESCRIPTION

FIG. 1 is a top perspective view of a modular building unit 2 or “pod” in accordance with one embodiment of the present disclosure. The pod 2 is provided in an initial location within a building structure 4. The building structure 4 may comprise a partially-constructed building unit. The building structure may have multiple levels or floors, such as a high-rise construction. The pod 2 can be provided in the initial location by, for example, a crane or similar lifting and moving device.

The pod 2 is any pre-fabricated structure intended to be installed in the building structure 4. In one embodiment, the pod 2 comprises a bathroom pod shipped to a site of the building structure 4. However, the pod 2 can be any structure that needs to be positioned and aligned within the building structure. An interior of the pod 2 may be partially or completely constructed. Regardless of the type of pod, the purpose of the pod, and the amount of materials or work required to finish construction of the pod, the pod 2 is ready for installation in the building structure.

The pod 2 is configured to be installed into a final location 6. More specifically, the pod 2 may be configured to align with features of the building structure, such as one or more walls and utility connections. Optionally, the final location 6 is proximate to a corner 7 of the building structure 4. Although positioning devices of the present disclosure can be used to position pods 2 in various final locations, FIG. 1 illustrates a situation in which the pod 2 is intended to be provided in a corner 7 of the existing room or structure 4. First and second walls 22, 24 of the pod 2 are intended to be provided in a predetermined alignment with a first wall 8 and a second wall 10 of the existing structure 4. In one embodiment, the walls 22, 24 of the pod 2 are configured to be flush with (or adjacent to) the first and second walls 8, 10.

One of skill in the art will recognize the various issues and challenges associated with placing the pod 2 in a corner location 7 which includes adjacent walls 8, 10. Methods and devices of the present disclosure are provided to simplify the installation procedures associated with moving a pod 2 to a final location 6. Further, the methods and devices of the present disclosure can be used to align the pod 2 with respect to existing utilities 12 (e.g. plumbing and electrical) of the building structure 4. More specifically, connections for the utilities 12 may be provided in one or more of the floor associated with the final location 6, walls 8, 10, and a ceiling of the building structure 4. The pod 2 can include connections that must tie into the existing utilities 12 of the building structure 4. Accordingly, the pod 2 must be moved from the initial location to the final location 6 and aligned with respect to the corner 7 and subsequently tied into connections for the utilities 12.

Referring now to FIG. 2, a top perspective view of an installation procedure and associated equipment related to a pod 2 and in accordance with one aspect of the present disclosure is provided. The pod 2 is illustrated in an initial position which comprises a non-final or uninstalled position. A final position 6 for the pod is shown. The final position 6 corresponds to a corner location 7 formed by at least two walls 8, 10 of the existing building structure 4.

A pallet 14 is shown as being separated from the pod 2 such that the pod is ready for installation in the final location 6. The pallet 14 is generally provided underneath the pod 2 during shipping and transit such that the pod 2 may be manipulated and moved using various known methods and devices (forklifts, straps, cranes, etc.). The pallet 14 comprises a contact point with the ground such that the pod 2 is elevated from the ground at least until it is ready for installation.

As one of skill in the art will appreciate, pallets 14 are frequently bulky and heavy. Further, as generally illustrated in FIG. 2, a pallet 14 may cover a significant amount of floor space within the building structure. Because of the size and weight of the pallet 14, it is difficult to separate the pallet 14 from a pod 2 and then remove the pallet from the building structure 4 with known lifting apparatus and methods.

In one embodiment of the present disclosure, lifting members 16 are provided in order to elevate the pod 2 above the pallet 14, remove the pallet 14, and generally render the pod 2 mobile. The lifting members 16 can be used to align the pod 2 with, and optionally, move the pod 2 into the final location 6. The lifting members 16 can be positioned on at least two free walls 18, 20 of the pod 2. The lifting members 16 may comprise various features for lifting the pod 2 and/or attaching wheels to the pod 2. U.S. patent application Ser. No. 15/236,184 to Nyce, filed on Aug. 12, 2016, and U.S. patent application Ser. No. 15/699,583 also by Nyce, filed Sep. 8, 2017, disclose various attachment and support devices for modular building structures, and are hereby incorporated by reference in their entirety. The lifting, moving, and supporting devices shown and described in U.S. patent application Ser. Nos. 15/236,184 and 15/699,583 are specifically contemplated for use with the systems and methods of the present disclosure.

FIG. 2 depicts a pod 2 that is prepared for installation. Once the pallet 14 has been removed from the pod 2, the pallet 14 may be removed completely from the work area and discarded or reused. The pod 2, which is now supported by at least one lifting member 16 on each of the two free walls 18, 20 of the pod 2, is ready for movement into the final position 6. The first and second walls 22, 24 of the pod 2 are ready for installation in alignment with walls 8, 10 of the building 4. The pod walls 22, 24 can be configured to be one or more of against, flush with, and adjacent to the building walls 8, 10.

Referring now to FIG. 3, a perspective view of a method and system for positioning and installing pods according to another embodiment of the present disclosure is provided. As shown, a pod 2 is provided in an uninstalled state thus requiring manipulation and movement prior to final placement and installation. An anchor member 30 of an embodiment of the present disclosure may be releasably interconnected to the pod 2 during the manipulation and movement of the pod. The anchor member 30 comprises a means for tilting and moving an associated pod 2. More specifically, the anchor member 30 can be used to facilitate lifting of the pod 2 one wall 20 such that a rear corner opposite to the free corner 26 does not drag on the ground during movement of the pod 2. Optionally, the anchor member 30 may be interconnected to one or more of walls 18, 20 of the pod 2.

The anchor member 30 generally comprises a skid 33 that is configured to receive ballast 32. Optionally, the skid 33 can include wheels (not illustrated). In one embodiment, the ballast 32 comprises commercially available metal plates. It will be recognized, however, that various devices or weights may be provided as ballast members for the anchor member 30.

The anchor member 30 comprises an anchor point 31. In one embodiment, the position of the anchor point 31 is adjustable vertically with respect to the skid 33. More specifically, in one embodiment, the anchor point 31 comprises a securing feature that is adjustable in at least a vertical direction.

The anchor point 31 comprises a connection point for at least one of a tension member 38 and an arm 34. Collectively, the arm 34 and the tension member 38 comprise a means to tip the pod 2, wherein a point of rotation of the pod 2 is centered about a connection between the adjustable arm(s) 34 and the pod 2. The anchor member 30 can be used to move a center of mass and a balance point of the pod 2 toward the anchor member.

The arm 34 extends between the anchor member 30 and the pod 2. In one embodiment, a pair of arms 34 are provided with the anchor member. Optionally, the arms 34 comprise an adjustability such that a length of the arms 34 may be selectively altered. In certain embodiments, the arms 34 comprise telescoping members that can be secured at a plurality of different lengths. Optionally, an arm 34 may engage a lifting member 16 associated with the pod 2. In one embodiment, the arms 34 include a hook to engage the pod 2 or a lifting member 16. Additionally, or alternatively, the arms 34 can engage a positioning device 50 described herein. The arms 34 are operable to receive one or more of compression and tension forces between the anchor member 30 and the pod 2.

The tension member 38 extends between the anchor member 30 and a portion of the pod 2. The tension member 38 is operable to receive a tension force. The tension member 38 can be connected to the pod 2 to provide leverage. The tension member 38 may be connected to any surface of the pod 2. Optionally, the tension member can be connected to a wall and proximate to the roof of the pod to maximize leverage. In one embodiment, the tension member 38 comprises one or more of a strap, a rope, a cable, and the like.

Optionally, an end of the tension member 38 associated with the pod branches into two tension portions. Each tension portion can be separately secured to the pod 2. Alternatively, two individual tension members 38 are interconnected to the anchor member 30 and the pod 2. The tension member 38 can optionally include a hook or clamp configured to interconnect the tension member to a pod.

The tension member 38 also comprises a tensioning device 36. The tensioning device 36 is operable to alter the length of the tension member 38 to adjust tension of the tension member 38. The tensioning device 36 can be used to level of a pod 2 to which the tensioning device is affixed by increasing or decreasing the length of the tension member 38.

The tensioning device 36 may be one or more of a hand-winch, a come-along cable puller, or a similar tension-applicator.

The recess is configured to substantially conform to a protrusion formed on the track 90. In one embodiment, the track 90 comprises an inverted “V” shape. In this manner, the track 90 reduces contact surface area and enhances movement of the positioning device 50, such as by ensuring the positioning device moves substantially parallel to the length of the track 90. The rollers or wheels 50 of the moving member 76 comprise a corresponding V-notch that interact with the track 90. The corresponding inverted “V” shapes also reduce the likelihood of a roller or wheel 78 becoming derailed or disconnected from the track 90. Other geometries of the track 90 and wheel 78 are contemplated for use with the positioning device 50 of the present disclosure.

In one embodiment, the moving member 76 includes a protrusion 80 for interconnection to a linkage 72. Optionally, the protrusion may be a hinge or pivot point. The linkage 72 extends from the protrusion 80 and is interconnected to the frame member (illustrated in FIG. 7A).

Referring again to FIGS. 7A, 7C, operation of the lifting mechanism 50 comprises lowering the frame member 52 by activating the drive member 82. In this manner, the frame member 52 and hooks 62 are lowered, as generally illustrated in FIG. 7C. In one embodiment, when the lifting mechanism is in the lowered state, the bottom portion 70 of the hooks 62 is a predetermined distance from the ground. The hooks 62 can then be rotated with the handle 60 into alignment with a support member of a pod 2.

Subsequently, the drive member 82 is activated in a reverse direction to lift the frame member 52 and hooks 62, such as generally illustrated in FIG. 7A, until the hooks 62 are engaged with the pod 2 and the pod is lifted from a floor or pallet. In one embodiment, the lifting mechanism is configured to raise a bottom surface of a pod 2 at least 0.4 inches above an upper surface of a pallet 14 when the lifting mechanism is in the raised state. Once the frame member 52 and pod 2 are lifted, the pod is free to roll or translate generally parallel to one or more walls 18, 22 associated with positioning devices 50 a, 50 b. Optionally, the positioning device 50 may move along the optional track 90, when present. The pallet 14 (if provided) may be easily removed from the workspace.

When the pod 2 is positioned in a desired location, the drive member 82 is operated to lower the frame member 52 and “land” the pod. The hooks 62 or connections to the pod 2 may thereafter be disengaged. The hooks 62 are then retracted such as to the position illustrated in FIG. 7B, by operating handle 60. In this manner, the positioning device 50 is disconnected from the pod 2. The positioning device 50 may then be rolled out or otherwise removed from the pod 2.

Although not shown in FIGS. 7A, 7C, positioning devices 50 of the present disclosure also contemplate the provision of various safeguards to prevent injury, such as that which may occur if a user or bystander were to become entrained in the moving components of the present invention. For example, in certain embodiments, an outer barrier is provided that includes a sheet of material to prevent ingress of body parts and other objects between the linkages 72. In further embodiments, a plurality of strands or strips (e.g. red or yellow tape) hang from a portion of the frame member 52 and provide a visual guide that users should remain clear of moving parts that are under heavy load.

While various embodiments of the system have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. It is to be expressly understood that such modifications and alterations are within the scope and spirit of the present disclosure. Further, it is to be understood that the phraseology and terminology used herein is for the purposes of description and should not be regarded as limiting.
